concrete

Hi. I decided that I'd place my fence posts inside sleeves, then fill with concrete / Postcrete. If I buy 200mm diameter tubing, that is made of 3mm thick cardboard, I'd be paying about £12, each for my sleeves (not incl. postage). That's £60 for 5 posts + postage on top. I may be able to use...

I'm planning a concrete driveway and have selected to use Dek Drain's aluminium edge "Slot Drain" drainage channels. I've checked the manufacturer's website, and although they don't say much about using it with concrete their installation guide shows two examples, one with block paving which...

Hi, thanks in advance for any advice. When we had a new front door installed, we also removed a low wall that previously sat beneath a window. This has left a hole in the floor, which is part of the cavity wall. I now need to fill this hole up to floor level in preparation for applying Mapei...

So our garden fence basically failed several months back when there were quite strong winds. The fence would be replaced with concrete posts instead of current timber ones. There is already a concrete post with a slot we can use at the end of the garden (facing direction of our fence), assuming...

Was going to lay membrane on a small external storage cupboard and gravel over with 20mm shingle/gravel. Then I started cleaning it up, removing the loose from the ground and it turned out to be more than expected and so am looking for ideas. Need to fill the voids with cement/ballast mix to...

I am planing on constructing a garden room (2.5 x 4m) at the back of my garden in an existing paved area. The room is a timber kit from Garden Buildings Direct. I am going back and forth on what to do about the base - the proposed area has existing paving which is not completely level as...

Hi, I've got a concrete base in my garden that's approximately 5m wide by 15m length. At one end there's a timber shed about 5m x 7.3m. I'm trying to think of what to do with the rest of the concrete base and thought about a 5m x 5m gazebo/outdoor kitchen to the other end, leaving 2.7m space...

Trying to work out whats actually necessary for a small indoor slab covering around 3x3 m. It is reinforced by a single layer steel grid and should be 5 inches thick. It isn't the final floor surface so doesn't need to be perfectly smooth. I am mixing the concrete myself. I have decided that...

I’m looking to fill in the cavity for my door threshold. I’ve read that I should be using a lean 1:8 cement, aggregate mix for foundation level strength however there is no mention of sand. Some other sources quote a 1:1:2 mix for this purpose. Should there be sand in the first mix? Which would...

This is my first post. Hope I'm in the right thread. I have an old concrete path that needs patching up. The house is about 100 years old and was built by the council. The concrete has tiny stones or aggregate in it that show through at the surface. Does anyone know how to create this? I've...

Hi After some advice on replacing my wooden frame, Perspex window in my concrete prefab garage with a UPVC unit. I plan to remove the entire window and its timber frame so all I am left with is the concrete panel edges. The end game for this garage is to get as close to this conversion as...

Hi all, I am doing up small front garden which currently has concrete everywhere - aiming to dig out a bunch of the concrete (as it currently goes right up to airbricks) and replace mostly with gravel. Trying to keep costs low where I can within reason and doing it myself. I had thought I...

Hi all. I need to build a small concrete pad 224cm x 86cm x 10cm for a new bin store. I always find it hard to calculate ballast and cement for concrete which I need to get to grips with. Can somebody help me work out my materials please? Thank you!

I’ve started a raised patio project and looking for advice regarding the retaining wall and steps. For the retaining wall I’m digging out 450mm wide and 300mm deep trench to put in a 150mm deep concrete footing in clay soil. The retaining wall will be approx 500mm above ground level. For the...

I'm building an extension on a sloped site which requires some underpinning. Just wondering if anyone has the best method to pour underneath the existing foundations as shown in this picture after the face shuttering goes on. Had various thoughts like creating a wedged gap to pour the concrete...

Morning, I've been reading through the searches on this topic and there are lots but all are slightly different to my situation. I've also been reading Paving Expert but i need some eyes on advice before I make a mistake. I'm planning on adding a gravel and stepping stone path to my garden, at...

Hi there! I'm new to the forum, and i wanted to get some advice. Several years ago, I helped my parents make an epoxy coated pebble patio for her back yard and the end result was absolutely gorgeous, and held up surprisingly well even through loads of rain (and one earthquake). I'm going to be...

Hi everyone – I'm looking for some advice on our 1910 solid brick wall terraced house in the UK which we are planning to renovate. Unusually, it has some prefabricated 105mm thick concrete dormers and I'm not sure how best to renovate them. We are in a conservation zone, so have no choice but...

Hi, I am a competent DIY-er but am finding it surprisingly difficult to get concrete numbers when trying to estimate how much cement, sand and gravel to buy for my project. The project is simple: I am extending a pre-existing concrete apron on which the car stands. I already have a good...

Hi all, I've been using the site for advice while planning my new patio and surrounding wall build. It's been very helpful, thank you all. One thing I'm still unsure about is how to extend my step down onto my patio, I'd like it to be full length, rather than the existing. My question is can I...
